Robert Venturi's 1966 book 'Complexity and Contradiction in Architecture' critiques modern architecture's failure to address urban and social issues post-WWII, advocating for an inclusive approach that recognizes complexity and contradiction in design. Venturi's work, framed within the cultural and political context of the 1960s, uses eclectic examples to illustrate how architecture should embrace ambiguity and the ordinary rather than striving for purity and heroism. The book is regarded as a foundational text for postmodernism, influencing architectural thought and practice for decades.
